“…The rotor speed due to the mechanical inertia varies smoothly during the accumulation of the excess of energy as kinetic energy in the rotor and during the decrease. Smooth fluctuations in the rotor speed are expected, but a change on the value of the rotor speed occurs if an augmentation or a decrease happens in the stored kinetic energy [37,38]. When the OWES is operating at nominal wind speed, if a wind sudden gust appears an increase in rotor speed is expected up to 10%.…”

“…Second, the use of a simple generator and power electronic interface restricts the control authority. Several technical control approaches and algorithms have been developed for the control of the interfacing system between the PMSG wind turbine and power grid [2]. Examples include deadbeat control [3], adaptive control [4], feedback linearization control [5], and fuzzy logic control [6].…”

Advanced control algorithms must be used to make wind power generation truly cost effective and reliable. In this study, we develop a new and simple control scheme that employs model predictive control (MPC), which is used in permanent magnet synchronous generators and grid-connected inverters. The proposed control law is based on two points, namely, MPC-based torque-current control loop is used for the generator-side converter to reach the maximum power point of the wind turbine, and MPC-based direct power control loop is used for the grid-side converter to satisfy the grid code and help improve system stability. Moreover, a simple prediction scheme is developed for the direct-drive wind energy conversion system (WECS) to reduce the computation burden for real-time applications. A small-scale WECS laboratory prototype is built and evaluated to verify the validity of the developed control methods. Acceptable results are obtained from the real-time implementation of the proposed MPC methods for WECS.

“…Power electronic converters are used to extract the maximum power and control electrical energy at constant frequency and voltage [1]. Various types of converters such as two-level PWM converters, matrix converters, and multilevel converters are described in different literature [2], [3]. These converters are designed to control the output voltage, current, and power for distributed load operation.…”

A single-stage AC-AC converter has been designed for a wind energy conversion system (WECS) that eliminates multistage operation and DC-link filter elements, thus resolving size, weight, and reliability issues. A simple switching strategy is used to control the switches that changes the variable-frequency AC output of an electrical generator to a constant-frequency supply to feed into a distributed electrical load/grid. In addition, a modified random sinusoidal pulse width modulation (RSPWM) technique has been developed for the designed converter to make the overall system more efficient by increasing generating power capacity and reducing the effects of inter-harmonics and sub-harmonics generated in the WECS. The technique uses carrier and reference waves of variable switching frequency to calculate the firing angles of the switches of the converter so that the three-phase output voltage of the converter is very close to a sine wave with reduced THD. A comparison of the performance of the proposed RSPWM technique with the conventional SPWM demonstrated that the power generated by a turbine in the proposed approximately increased by 5% to 10% and THD reduces by 40% both in voltage and current with respect to conventional SPWM.
